In Sinaloa we have no very definite account of ruins. However, Mr. Bandelier says, the existence of ancient villages in that section is certain, and that from “Sinaloa there are ample evidences of a continuous flow Southward.”24 There are no ruins worth mentioning in any of the other States, excepting Zacatecas, where we find a ruin of great interest. This is at Quemada, in the southern part of the State. The name is taken from that of a farm in the near neighborhood. The ruins are situated on the top of a hill, which is not only naturally strong, but the approaches to it are fortified. The hill ascends from the plain in a gentle slope for several hundred yards, it then rises quite precipitously for about a hundred and fifty feet. The total height of the hill above the plain is probably not far from eight hundred feet.25
At all points where the approach to the top of the hill is not steep enough to form a protection of itself, the brow is guarded by walls of stone. This is especially true of the northern end of the hill. One peculiar feature of this place is the traces of ancient roads, which can still be clearly distinguished crossing each other at various angles on the slope we have mentioned. They can be followed for miles, and are described as being slightly raised and paved with rough stones. In places on the slope, their sides are protected by embankments.
Considerable speculations have been indulged in as to the purposes for which these roads were used. It has been suggested that they were the streets of an ancient city which must once have existed on the plains; and that the fortified hill, with the ruins on its summit, was the citadel, the residence of their rulers, and the location of their temples. But we think a more reasonable view is that all of the city that ever stood in that neighborhood was on the hill summit, and that these streets were for religious purposes, reminding us in this respect of the graded ways and traces of paved streets sometimes met with in the Mississippi Valley. In proof of this view, it is said that many of them, after being followed for a long distance, are found to terminate in a heap of stones, which are evidently the ruins of a regular pyramid. In opposition to both of these views, it has been suggested that the surrounding plain was low and marshy, and that the object of these causeways was to secure a dry passage, which explanation is certainly very reasonable.
Of the top of the hill, it may be sufficient to state that it is of irregular shape, half a mile in length from north to south, and of varying width, but on an average one thousand feet wide. The approach to the top of the hill was strongly guarded. Although buildings were observed covering the whole top of the hill, yet they were in two principal groups. This cut, though but one of many, will give us very good ideas of all the ruins. It is seen to be an inclosure. It is on a small scale. It was one hundred and fifty feet square. We notice terraces on three sides. These terraces are three feet high by twelve wide, and in the center of each side are steps by which to descend to the square.26 Each terrace is backed by a wall, portions of which are seen in the engraving. These walls are twenty feet high by eight or nine in thickness. The openings seen in the wall are not properly doors, as they extend to the top of the wall.
This court, encompassed by terraces, is a peculiar feature. It is different from any thing we know of, either north or south.27 Courts, surrounded by buildings located on terraces, are common enough, but all accounts of these ruins say nothing of buildings. We remember the inclosures that surrounded the houses clustered in groups on the Rio Gila. We think this comes near to being a development of the same idea. The low walls of the former inclosure are here quite pretentious pieces of masonry. In some cases two or more of these inclosed courts are joined by openings.
The opening in the wall on the right of the engraving leads into a perfect inclosed square of two hundred feet. In one case a range of pillars was noticed parallel with the walls, and distant twenty-three feet. These are supposed to have supported the roof of the portico, and houses of a rude description might have been ranged along under this roof, which has since completely vanished. Back of this square, but not very well shown on the drawing, rises a precipitous hill. A pyramid is placed in the center of the side towards the hill. It is only nineteen feet high,28 but is divided into five stages or stories.29
This pyramid will serve as an example of numerous other pyramids scattered over the summit of the hill. They are made of stone. The largest one, whose dimensions are given, is fifty feet square, and the same in height. In front of the pyramid, and in the center of the square, are the remains of an altar. In view of the altar and pyramid, within the inclosed square, we may suppose this to have been dedicated to their religion. As if to confirm this belief, is the statement that on the hill to the back of the pyramid are numerous tiers of seats, either broken in the rock or built of rough stone. The people seated on them would be conveniently located as regards both sight and hearing of what transpired there.
From an Indian’s point of view, this hill was very strongly fortified. It would be almost impossible for an enemy to capture the settlement on its summit. The surrounding country was probably fertile, and a large body of Indians could have lodged within the fortified inclosures. It has some peculiar features, which have been pointed out. There is now no water on the hill, but traces of what is supposed to be an aqueduct are observed, as well as several tanks, and at one place a well. There is not an appearance of great antiquity about these ruins, and yet native traditions are silent in regard to them, and but one of the early writers refers to them, and he had not seen them.30
